"Coat" - what is it, definition of the term
A coat is a removable outer garment composed of fabric, leather, or synthetic material that serves as a protective barrier against temperature extremes, wind, and precipitation; in biological terminology the word also describes the integumentary covering that shields arthropods such as ticks, bugs, lice, and fleas.
Detailed information
The term “outerwear” refers to a garment designed to be worn over other clothing for protection against environmental factors. Typical constructions involve a body panel, sleeves, and a closure system such as buttons, zippers, or toggles. Materials range from natural fibers (wool, cotton) to synthetics (polyester, nylon) and blends, each offering distinct thermal, moisture‑wicking, and durability characteristics.
Parasitic arthropods—ticks, insects, lice, and fleas—can become lodged in the fibers of an overgarment. Their presence is facilitated by loose weaves, untreated surfaces, and prolonged exposure to infested environments. Infestations may lead to skin irritation, allergic reactions, or vector‑borne disease transmission.
Selecting pest‑resistant fabrics reduces colonization risk. Effective options include:
- Tightly woven synthetics with a thread count exceeding 200 threads/inch.
- Fabrics treated with permethrin or other approved insecticidal agents.
- Hydrophobic finishes that discourage moisture accumulation, a condition that attracts many ectoparasites.
Maintenance protocols further limit infestation:
- Wash the garment at the highest temperature recommended by the manufacturer; temperatures of 60 °C (140 °F) or higher deactivate most ectoparasites.
- Use a detergent containing an insect‑killing additive when available.
- Dry on a high‑heat setting for at least 30 minutes to ensure complete eradication.
- Inspect seams, cuffs, and interior pockets after each use; remove any visible organisms promptly.
- Store in a sealed, low‑humidity container; consider adding silica packets to maintain dryness.
Regular rotation of outerwear prevents prolonged exposure of a single item to contaminated areas, thereby decreasing the likelihood of parasite buildup. Implementing these material choices and care procedures ensures the garment remains effective for protection while minimizing health hazards associated with ticks, bugs, lice, and fleas.
